[Bug 1583288] Re: Realtek Wifi card rtl8723be [10ec:b723] WiFi not available

 

apport information

** Tags added: apport-collected rosa

** Description changed:

  I am here on a HP Pavilion Laptop with beatsaudio. No Model Number -
  nothing.But I have this problem on other HP (455) Notebooks too.
  
  OS tried: OpenSuse / Kubuntu / Linux Mint Mate (card does not work out
  of the box / no scanning)
  
  The Wifi card is: (in Germany!)
  
  --------------------------------------
  
   lspci -nn | grep -iA2 net
  02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]
  
  --------------------------------------
  
  I am now under kernel:
  4.4.0-21-generic
  
  I installed the newest kernel because in some threads people said the card woule be available in the newest kernel. But this was not the case. I mean the card is there but does not scan nor see any wifi networks.
  -------------------------------------
  
  Before I tried everything I could find to get my wifi running but I do
  not even see one spot. So no connection at all. I even cloned git and
  compiled the driver - the compiling and installation worked fine. I
  tried the old and the new driver.
  
  By the way the BT seems to be fine - although I have not checked cause I
  do not need BT.
  
  ---------------------------------------------
  Here is what I tried:

  -------------------------------------
  
  I added the options sugested in rtl8723be.conf
  
  options rtl8723be fwlps=0 swlps=0
  
  But this did not help either.

  ---------------------------------
  
  no errors but no change.
  
  ---------------------------------
  
  Checked this link:

  ---------------------------------
  
  Then I tried several params and finally this worked somehow.
  
  sudo modprobe -rv rtl8723be
  
  sudo modprobe -v rtl8723be msi=1
  
  I now was able to see wifi networks - hoorayyyy!! :)
  
  ---------------------------------------------------------
  
  I then tried to connect to my network - but failed.
  
  I am sitting 1 m next to my router.

  WORKAROUND: I changed region to Germany:
  echo 'KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/iw reg set DE"' | sudo tee /etc/udev/rules.d/regulatory.rules
  
  and then I was able to connect. My options are now:
  options rtl8723be fwlps=0 swlps=0 msi=1
  
  Now it runs perfectly! Thanks to all!!

  Incomplete

  ---------------------------------------
  WORKAROUND: I changed region to Germany:
  echo 'KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform", RUN+="/sbin/iw reg set DE"' | sudo tee /etc/udev/rules.d/regulatory.rules

  and then I was able to connect. My options are now:
  options rtl8723be fwlps=0 swlps=0 msi=1

  Now it runs perfectly! Thanks to all!!
